Application fried J'u1y. 17, 1908. Serial No. 444,025.

To all whom it may concern. A

Be it known that I, GEORGE W. BOON, a citizen oi the United States,residing at Kerens, in the county of Randolph and State of WestVirginia, have invented a new and use I fuLRailWay-Switch, of which thefollowing is a s ecification.

hls invention relates to railway switches and its object is to provide aconstruction in I reference, 1; 2 and 3 means of plates 11 bolted orvFig. 2 is a section-on line A+B, Fig.1..

which frogs such as usually employed are eliminate Another object is toprovide simple mechanism for shiftin the'switch rails and the switchtongue uti ized.

A further object is to provide a switch util- 1zing a movable tongueand-movable switch rails all of whichcoo crate to close either'the maintrack orthe si ngtrack.

With these and other objects in viewthe invention consists of certainnovel features construction and combinations of parts which will behereinafter more fully described and pointed out in the claims. Intheaocom the preferred form of'the invention.

In said drawingszzFigure 1 isaplanv'iig w. 3 is an elevation of themeeting ends of tlie switch tongue and the adjoining main line rail, theconnecting late being removed.

Referring to the res by characters of designate main line rails all ofwhich are inimovably fastened place and the rail 3 merges into'a'curvedsiding rail 4 which'is also immovablysecu'red in place as t is the otheror inner si t r.ail'5 which extends at an acute angle from the end ofthe inner main line rail 2. A guide plate 6'is.se-'

cured upon the ties 7 between the'rails 1 and 4 and said plateintersects .thel ne occupied by the rails 2 and 3, there being a slot 8within the guide plate for the reception of a retain in in 9 extend'downward from a tongue 10 vhich is in th e f brm of a short railsecuredto the meeting ends of the rails 2 and '5 by otherwise secured to saidrails and to 0p osite faces of the tongues 10. As indicate in 3 thetongue is preferably provided with a slot 12 so that a suflicient amountof. lay thereof relative to the rails 2 and 5'andt e plates 11 ispermitted. Switch rails 13 and nected at one end to the plate 6 b meansofv pivot pins the pivot of the rail 13 being 'disposed'in alinementwith the rails '2 and 3 ying drawings is shown 14 are conwith main linerails and siding rails, one of 1 line extending parallel with the rail 4from the rail 5 to the rail 1. The switch rail 14 is slightly curivedfrom'one end so that whenits free end, which is reduced in width andtapered as indicated at 15, is shifted against the rail 1 said; rail 14will be parallel with the rail 4. The two rails 13 and 14 of coursediverge toward their free ends, said end of the rail 13 being graduallyreduced in width as indicated at 16 so as to fit snugly against themerged portions of the rails 3 and 4. These reduced ends 15 and 16 ofthe rails 14 and 13 are connected by a cross bar 17 which ivoted to oneend of a bell crank lever 18. rod 19 is ivotally connected to the otherend of this ever and to a crank 20 arranged upon the shaft 21 anddisposed to be actuated by means of a lever 22. Another rod 23'is pivotally connected to lever 18 and also to one end of a bell crank'lever 24which has a bar'25 attached to it; This bar extends under the plate 6and is pivotally mounted upon the re taining pin 9 as shown in Fig. 2.

The levers are so proportioned that when lever 22 is'swung in onedirection. the end 16 of rail 13 will be shifted against the rail 3 andinto alinement with said rail and the rail- 2 while the tongue 10 willat the sametime be swung in position between the rails 2 and- 13v andinto alinement therewith. During 'this movement of the parts the rail14- is shifted away from the rail 1. The switch thus becomes closed. Toopen the switch so s to direct a car onto the siding the forego ingoperation of lever 22 is reversed and motion is therefore transmittedthrough the rods 19 and 23 and the lovers 18 and 24 to the bars 17 and25 so as to-shift rail 13 out of contact with-the rail 3 and to move theend15 of rail 14 into contact with the rail 1. At the same time thetongue 10 will be shifted between and into. alinement with the rails 5and '14.

It be seen that with this arrangement of parts it becomes unnecessary toutilize frogs such as ordinarily, employed and not only is the mechanismextremely simple and durable in construction 'but it practicallyeliminates all danger of derailment at the switch.

7 What is claimed is: .1. In a railway'switch' the combination thesiding rails merging into one of the main I line rails and all of saidrails beingimmovably'mounted of a tongue extending beyond the meetingends of the inner main line and thereto, switch rails pivotally mountedbeline and siding and adjacent the path of the tongue, and means forsimultaneously shifting the tongue 'and switch rails to position thetongue tween the rails of the 'main against the pivot end of one of therails to open or close the siding.

2. In a railway switch the combination with main line and siding'rails,one of the siding rails merging into amain line rail and the inner oradjoining main line and siding rails meeting at an acute angle; of atongue extending beyond and pivotally connected to said inner rails,said tongue being shiftableinto alinement with eitherv of said innerrails, switch rails .pivotally mounted between the main. line and sidingrails and close to the path of the free end of the tongue, and means forsimultaneously shifting the tongue and the switch rails to open or closethe switch, said tongue being movable against the pivoted end of eitherswitch rail.

v3. In a railway switch the combination with main line and siding rails,the inner or adjoining rails of the main line and siding being broughttogether at an acute angle; of

switch rails pivotally mounted between the main line and siding railsand adjacent said angle, means for shifting the switch rails to open orclose the connected to and extending beyond the inner rails of the mainline and siding, and means for shifting the said tongue into alinementwith and against either switch rail during the movement of said switchrails.

4. A railway switch comprising main line and siding rails, the inner oradjoining rails of said main line and siding being disposed together atan acute angle to each other, a

guide member secured between the main line and siding rails, a tonguemovably connected siding, a tongue pivotally to the inner rails of themain line and siding and movable upon said guide member, switch railspivotally mounted upon the guide member, and means for simultaneouslyshifting the switch rails and tongue to open or close the siding.

5. A railway switch comprising main line. and siding rails immovablymounted, the inner or adjoining main line and siding rails be ingbrought together at an acute angle a slotted guide plate, a tongueextending econnected to the meeting yond and movably ends of the innerrails, said tongue bearing upon the guide plate, "retaining means uponthe tongue and movably mounted within the plate, switch rails pivotallymounted upon said plate, and means for simultaneously shifting the railsand tongue to position the tongue in alinement with either switch railt'o open or close the siding.

6. A railway switch comprising main line b and siding rails, the inneror adjoining rails of the mainline and siding being brought t'o-' 1gether at aeuteangle, a tongue movably connected to and extending beyondthe meeting ends of the innerrail, a slotted guide plate therefor,retaining means upon the tongue and mounted to travel within the slot,switch rails pivotally mounted u on the plate, against the rails of themain line, and means for simultaneously shifting the switch rails andthe tongue to position the tongue inalinement with either switch rail toopen or close the siding.

In testimony that [claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
